Default Work hardening of alloy cones

I have been wondering about the effect of work hardening of alloy cones as part of the break-in process! I think it makes sense that aluminum cones will stiffen up over time as work hardening takes place. Any thoughts on this?

Unlikely...work hardening requires that the elastic limit of the material be exceeded in order to produce inelastic deformation. The stress level in an aluminum speaker cone would be far below the elastic limit.
